Smoking pipe



5. CHADKIN SMOKING PIPE July 3, 1934.,

Filed Dec. 30, 1932 INVENTOR jar/Yard (/zaa/h ll BY W W ATTORNEY WITNESSES 22M .q/w r/Le Patented July 3, 1934 PATENT oFFicE UNITED STATES 1 Claim.

This invention relates to smoking pipes and has for an object to provide an improved construction wherein, if desired, substantially the usual form of pipe may be provided but with means for causing the smoke to move out of the stern and then back into the stem as it travels from the bowl to the discharge end of the mouthpiece.

Another object of the invention is to provide a smoking pipe wherein tubular means are pro-- vided which may be set into the stem of the smoking pipe or may be wrapped around the same to conduct the smoke from part of the stem to a point outside thereof and then back into the stem or into the mouthpiece, the tubular members being sufiiciently long to cool the smoke as it passes out of and then into the stem.

An additional object, more specifically, is to provide a smoking pipe having substantially the usual bowl, stem and mouthpiece. together with tubular members having both ends extending through the stem at spaced points, one point being located so as to register with the opening in the mouthpiece whereby the smoke from the stem will move out of the stem and then back through the stem into the mouthpiece for cooling purposes.

In the accompanying drawing- Figure l is a top plan view of a pipe disclosing an embodiment of the invention;

Figure 2 is an enlarged sectional view through Figure 1 approximately on the line 2-2;

Figure 3 is an enlarged transverse sectional view through Figure l on the line 33;

Figure 4 is a View similar to Figure 2 but showing a modified construction;

Figure 5 is a transverse sectional view through Figure 4 on the line 55.

Referring to the accompanying drawing by numerals, 1 indicates the bowl of a pipe which may be of any desired construction, and 2 an integral stem. Associated with the stem 2 is a mouthpiece 3 which may be slidingly mounted in place as shown in Figure 2, or may be threaded in place or otherwise held in place as desired.

As shown in Figures 1 to 3, there are provided 45 tubular members or small pipes 4 and 5 for moving the smoke out of the stem at one point and back into the stem at another point. As illustrated particularly in Figure 2 and Figure 3, the pipe or tubular member 4 extendsthrough one 5 wall of the stem 2 at point 6 so as to receive the smoke as indicated by the arrow '7. The smoke passes along the tubular member and out through the extension 8 fitted into an aperture 9. It will e noted that aperture 9 is in the stem 2 but is in alignment with aperture 10 of the mouthpiece 3. Also a clamping screw 11 is provided which is screwed into the mouthpiece 3, said clamping screw being formed with a bore 12 having an aperture or opening 13 for registering with the aperture or opening 10, thus permitting the smoke passing as indicated by the arrow '7 to and through passageways l0 and 13 so as to discharge into the bore 12, which in turn discharges into the smoke passageway 14 of mouthpiece 3.

As shown in the accompanying drawing, two tubular members 4 and 5 have been illustrated, but it will be evident that one or more than two could beused without departing from the spirit of the invention. The spacing of these tubular members may be as shown in the drawing, or they can be arranged closer together or further apart, and yet come within the spirit of the invention. When the parts are assembled as shown in Figures 1 and 2 the pipe is ready for use. Whenever desired, the mouthpiece 3 can be readily pulled from the stem 2, and then if desired the member 11 can be unscrewed and removed. This operation is usually done when the pipe is to be cleaned.

t will be noted that the tubular members 4 and 5 are slightly embedded in the stem 2, but they might be further embedded or not embedded at all and still remain within the spirit of the invention, as the invention is to provide a passageway outside of the stem 2 so as to. secure a cooling action. 3

In carrying out this idea of having the same inventive idea presented in slightly different structures, attention is called to Figures 4 and 5 wherein it will be seen that there is used a single tubular member 15 arranged in a coil with the ends 16 and 17 extending through the stem 2 in a similar manner to the way the ends are fitted in Figure 2. Aside from the fact that the coiled structure is used in Figure 4, the construction is identical with that shown in Figure 2 and the same reference numerals will apply except that the coil is numbered 15. As the smoke passes through this coil it is outside of the stem and consequently is cooled before it enters the passageway 14. By having both ends of the coil extending through the stem 2 and not through the mouthpiece 3 results in permitting the mouthpiece to be readily applied and removed at any time without affecting in any way the tubular structure 15 or the tubular structures 4 and 5, as shown in Figures 1 and 2.

In forming the tubular members they may be of the length shown in the drawing, or they be substantially the full length of the stem 2. Also, these tubular members may be arranged as shown in the drawing, or positioned closer to or further from the bowl 1. By arranging the tubular members exposed to the air outside of the stem it will be seen that the smoke will be readily cooled as it passes from the bowl to the discharge end of the mouthpiece.

I claim:-

A smoking pipe provided with a bowl having a hollow stem, a mouthpiece provided with a passageway having a plug in one endrformed with a tubular portion open at one end, said open end registering with the passageway in said stem, said mouthpiece having a reduced portion carrying said plug and its extension, said reduced portion and stem fitting into one end of said stem for closing the same, said reduced portion and BERNARD CHADKIN.
